Kask Nirvana WG11 Cycling Helmet

Kask's top-tier helmet gives you a speed boost. Proven in the UCI World Tour, the Kask Nirvana WG11 Cycling Helmet pushes the boundaries of cycling speed. Fusing elements from their time trial helmets with their aero road helmets, it hits the perfect spot between watt-saving performance, airy comfort and reliable safety.

Aero Gains

An immediately obvious feature is the deep aero shell, similar to a TT helmet, partially covering the ears. This extra fairing creates a far more aerodynamically efficient profile, keeping drag to a minimum. Pick up speed and enjoy the watts savings.

While optimised for speed, ventilation hasn't been overlooked. Front vents are carefully positioned to suck air into internal channels which then lead to a large rear exhaust vent. This gives targeted airflow across your head, keeping you cool when it's time to press hard on the pedals.

If you're after the numbers, Kask claims a 35% reduction in aerodynamic drag and a 19% increase in ventilation compared to the best aero helmets in its class.

Tuned Safety 

Kask takes their 3D-printed Mutlipod internal padding system from their Elemento and applies it to the Nirvana. This proprietary technology utilises an isotropic elastomer material to absorb and dissipate linear and rotational impacts. Thanks to its ability to absorb forces in any direction it improves safety should you crash.

The well-proven Kask OCTOFIT+ system is also present, giving you quick and easy adjustments via a highly adjustable dial and supportive vertical cradle system. The system offers unrivalled comfort, greater helmet stability when riding and safety you can trust. 

Kask WG11 Rotational Impact Test Protocol 

WG11 is Kask's own rotational impact test protocol. The objective is to create helmets that keep you safer in the event of a crash. WG11 aims to more closely mimic the real-life conditions of head impacts than current industry testing. The "pass-fail" criterion is based on the BrIC value, an algorithm defining the level of brain injury. This value must be lower than 0.68. All Kask WG11 cycle helmets pass this figure, with values substantially less than the target.
